Dolomite Powder
Manufacturers in India
Vrindavan Minerals is a leading dolomite powder manufacturer and bulk supplier in Udaipur, Rajasthan, providing high-purity calcium-magnesium carbonate CaMg(CO3)2 for glass, paint, ceramics, rubber, and agriculture.
What Is Dolomite Powder?
Dolomite powder is a fine mineral powder made from crushing calcium magnesium carbonate (CaMg(CO3)2). It is widely used in gardening to neutralize acidic soil and supply vital calcium and magnesium, as well as in industrial manufacturing for paints, ceramics, glass, and wall putty.
It is produced from dolomite rock, a naturally occurring double carbonate of calcium and magnesium that forms in sedimentary deposits over millions of years and is mined much like limestone. The added magnesium makes dolomite powder harder and more weather-resistant than plain calcium carbonate. Combined with natural whiteness, chemical stability and low oil absorption, this makes it one of the most widely used functional fillers in Indian industry.
Dolomite Powder vs Calcium Carbonate
Both are white mineral fillers, but dolomite carries magnesium carbonate as well as calcium carbonate. That gives it extra hardness and better weathering performance, while calcium carbonate is softer and usually more economical for lower-demand uses. Dolomite works as an extender, an opacifying agent and a cost-effective substitute for higher-priced minerals such as titanium dioxide. See our Calcium Carbonate Powder page for a full comparison.

Agriculture Grade
Coarser mesh powder for neutralizing acidic soil and supplying calcium and magnesium to crops.
Dolomite Powder Mesh Size Guide
Coarser mesh suits agriculture and construction, while finer mesh gives the smooth dispersion and surface finish that paints, plastics and rubber need.
Dolomite Powder for Agriculture and Gardening
Dolomite powder is one of the most common soil amendments for acidic soil, used by farmers, nurseries and home gardeners alike.
How It Improves Soil
The carbonate in dolomite reacts with the hydrogen ions that cause soil acidity, raising soil pH. It also supplies calcium for soil structure and magnesium, which plants need to form chlorophyll.
Dolomite vs Garden Lime
Both raise soil pH, but garden lime adds only calcium, while dolomite adds calcium and magnesium. This makes dolomite the better choice for magnesium-deficient soil, though it is generally slower acting.
Application Tips
Base the quantity on a soil test to avoid over-liming, spread evenly on dry soil before planting, and wear a dust mask while handling the powder. Coarser mesh is usually sufficient for this use.
Dolomite Powder Manufacturing Process
Turning raw dolomite rock into a consistent, application-ready powder involves several controlled stages. Exact parameters vary by grade and mesh requirement, but the process generally follows four steps from mine to finished bag.
Mining & Selection
Dolomite boulders are extracted from Rajasthan's Aravalli belt and sorted to remove low-purity or discoloured rock before it enters processing.
Crushing & Drying
Selected rock is crushed into smaller chips and dried to remove surface moisture, which is essential for stable whiteness and preventing lump formation.
Grinding & Mesh Grading
Dried material is ground in ball mills or micronizers and screened to the required mesh size, from coarse 100 mesh to fine 1250 mesh.
Testing & Packing
Each batch is tested for whiteness, chemical composition and moisture before being packed into moisture-resistant bags for dispatch.
Aravalli Mineral Belt
Direct proximity to Rajasthan's dolomite reserves keeps our sourcing and quality control tight.

Dolomite Powder Manufacturers in Rajasthan
Rajasthan is home to some of India's most significant dolomite reserves, particularly across the Aravalli belt that runs through Udaipur, Rajsamand and neighbouring districts. This is why dolomite powder manufacturers in Rajasthan are concentrated in and around Udaipur, with direct access to high-purity raw material and no long-distance freight cost on rock.
Dolomite Powder Suppliers in India
As a dolomite powder manufacturer in Udaipur, we receive raw rock quickly and check quality close to the source, giving tighter control over whiteness and chemical consistency than units that depend on distant quarries. Vrindavan Minerals runs its own crushing, grinding and screening facility rather than acting as a trading intermediary, which makes us one of the dependable dolomite powder suppliers in India for paint, plastic, rubber, glass, ceramic, agriculture and construction buyers, with shorter dispatch timelines across Rajasthan, Gujarat, Madhya Pradesh and beyond.
How to Choose Dolomite Powder Manufacturers and Suppliers in India
Not every supplier controls the process from raw rock to finished mesh. These checks help you compare dolomite powder manufacturers in India on what actually affects your product.
Quality Factors To Check
Before finalising an order, ask any dolomite powder supplier for a current test certificate covering four essentials: whiteness percentage, chemical composition (CaO, MgO and SiO2), moisture content, and mesh or particle size distribution. These figures determine how consistently the powder will disperse, how much it will affect the final colour of your product, and how it behaves during processing.
Also check batch-to-batch consistency rather than relying on a single sample report. Ask whether the supplier tests every dispatch or only periodic batches, and confirm packaging, since moisture-resistant HDPE bags with proper liners protect the powder in transit, especially over long distances or humid conditions.
Choosing A Manufacturer
India has no shortage of dolomite powder manufacturers, but many operate as traders who buy semi-processed material and simply repack it, which makes it harder to guarantee mesh accuracy or chemical consistency order after order. Working directly with a manufacturer that mines, crushes, mills and screens its own material generally means tighter quality control and more transparent pricing on bulk volumes.
Look for a track record of pan-India dispatch, clear batch documentation, support for both small trial orders and recurring bulk volumes, and the flexibility to produce custom mesh sizes. Vrindavan Minerals combines in-house processing with batch-wise testing from our Udaipur facility, giving buyers a dependable dolomite powder manufacturer in Rajasthan for consistent grade, timely dispatch and responsive technical support.
Dolomite powder remains one of the most versatile mineral fillers used across Indian manufacturing, from paints and PVC to rubber, glass, ceramics, agriculture and construction. Consistent results depend less on the mineral itself and more on choosing a supplier who documents whiteness, chemical composition and mesh size on every batch. As dolomite powder manufacturers in Udaipur, Rajasthan, Vrindavan Minerals combines direct access to raw material with in-house processing and testing, so buyers across India can source paint grade, plastic grade and industrial grade dolomite powder with confidence.
Dolomite Powder FAQs
Dolomite powder is used as a soil conditioner in agriculture and gardening, and as a filler or flux in paints, wall putty, plastics and PVC, rubber, glass, ceramics, cement and other construction materials. We supply it in 100 to 1250 mesh to suit each of these uses.
Vrindavan Minerals is one of the established dolomite powder manufacturers in India, processing dolomite rock into paint grade, plastic grade, and industrial grade powder at our own facility in Udaipur, Rajasthan, with pan-India and export supply. Unlike traders who repack semi-processed material, we control every stage from mining to mesh grading, which allows us to document whiteness, chemical composition and moisture content on each batch we dispatch.
Udaipur sits close to some of India's richest dolomite mineral belts, so a dolomite powder manufacturer in Udaipur like us can control quality from raw rock to finished powder, keep mesh sizes consistent, and offer shorter lead times to buyers across Rajasthan and neighbouring states. This proximity to the raw material also helps keep pricing more stable compared to units that depend on rock transported over long distances.
Most dolomite powder manufacturers in Rajasthan, including Vrindavan Minerals, supply standard mesh sizes of 100, 300, 500, and up to 1250, with custom micron sizes available on request. Coarser mesh is common in agriculture and construction, while finer grades are preferred for paint, plastic and rubber formulations that need smooth dispersion.
Look for dolomite powder suppliers in India who share whiteness percentage, chemical composition (CaO, MgO, SiO2), and mesh size test reports upfront, and who can package to your volume needs, from 25 kg bags to 1-ton jumbo bags. Also confirm whether they test every batch or only periodic samples, since this affects consistency across repeat orders.
Paint Grade Dolomite Powder is milled for high whiteness and low oil absorption to work as a paint and putty extender, while Plastic Grade Dolomite Powder in India is processed for fine particle dispersion and rigidity, suited to PVC, pipes, and rubber compounding.
